Warning: Experts have suggested that every hour of watching TV shortens life expectancy by 22 minutes.

　　Every hour spent watching TV, DVDs and videos as an adult reduces life expectancy by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years.

　　一項(xiàng)研究指出，成年人每看一小時(shí)電視、DVD或視頻就會(huì)減少22分鐘的壽命。每天平均看6小時(shí)電視會(huì)減壽5年。

　　The research claims that a sedentary lifestyle is as bad for health as smoking and obesity, because of the dangers posed by inactivity and the greater opportunities it offers for unhealthy eating.

　　該研究稱，久坐的生活方式就跟抽煙和肥胖一樣有害身體健康。因?yàn)榫米鴷?huì)對(duì)健康造成威脅，也會(huì)增加不良飲食的機(jī)率。

　　The academics conducting the study set out to calculate the overall risk to life expectancy from watching television. Their research involved more than 11,000 people over the age of 25.

　　學(xué)者們開展此項(xiàng)研究的目的是為了估算看電視對(duì)壽命的總體風(fēng)險(xiǎn)。他們的研究對(duì)象涵蓋了年齡在25歲以上的1.1萬多人。

　　Writing in the British Journal of Sports Medicine, they concluded: ‘TV viewing time may be associated with a loss of life that is comparable to other major chronic disease risk factors such as physical inactivity and obesity.’

　　他們?cè)谟?guó)《運(yùn)動(dòng)醫(yī)學(xué)》雜志上的文章得出結(jié)論說：“看電視的時(shí)間長(zhǎng)短可能與壽命減少有關(guān)，而且這一因素并不亞于其他導(dǎo)致慢性疾病的主要風(fēng)險(xiǎn)因素，例如缺乏運(yùn)動(dòng)和肥胖。”

　　The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data.

　　昆士蘭大學(xué)的研究人員采用了來自澳大利亞糖尿病、肥胖和生活方式研究的數(shù)據(jù)，以及澳洲人口和死亡率的數(shù)據(jù)。

　　But they said: ‘While we used Australian data, the effects in other industrialised and developing countries are likely to be comparable, given the typically large amounts of time spent watching TV and similarities in disease patterns.’ In the UK, the average amount of time spent watching TV is four hours a day compared with five hours in the United States.

　　他們說：“盡管我們用的是澳大利亞的數(shù)據(jù)，但其影響同樣適用于其他工業(yè)化和發(fā)展中國(guó)家，因?yàn)檫@些國(guó)家的人們通常看電視的時(shí)間也很多，疾病類型也比較相似。”在英國(guó)，人們平均每天花4小時(shí)的時(shí)間看電視，而美國(guó)人則每天看5小時(shí)電視。

　　Researchers from the Harvard School of Public Health, Boston, said it was ‘biologicallyplausible’ that prolonged TV viewing results in disease and premature death. Other work suggests that sedentary behaviour is linked to obesity, high levels of bad blood fats and other heart disease risk factors, and more opportunities for grazing on junk foods.

　　位于波士頓的哈佛公共健康學(xué)院的研究人員說，看電視時(shí)間過長(zhǎng)會(huì)導(dǎo)致疾病和早死，這在生物學(xué)上是講得通的。其他研究也顯示，久坐這一行為方式與肥胖、高血脂等多種心臟病風(fēng)險(xiǎn)因素相關(guān)，還會(huì)讓人攝入更多垃圾食品。

　　Earlier this year, a separate study suggested the risk of developing type 2 diabetesand heart disease, or dying prematurely, rises by as much as 20 percent after just two hours a day in front of the box.

　　今年早些時(shí)候的一項(xiàng)獨(dú)立研究發(fā)現(xiàn)，每天坐在電視機(jī)前2小時(shí)，患II型糖尿病、心臟病或過早死的機(jī)率就會(huì)上升20%。

　　England’s Chief Medical Officer, Sally Davies, said: ‘Physical activity offers huge benefits and these studies back what we already know – that a sedentary lifestyle carries additional risks. We hope these studies will help more people realise that there are many ways to get exercise.’

　　英格蘭首席衛(wèi)生官莎莉?戴維斯說：“體力活動(dòng)會(huì)帶來極大的好處，這些研究也支持了我們?cè)缫阎赖氖虑椋簿褪蔷米纳罘绞绞俏ｋU(xiǎn)的。我們希望這些研究能幫助更多人意識(shí)到鍛煉的方式有很多種。”

　　Another study shows that exercising for just 15 minutes a day can increase your lifespan by up to three years. It can reduce the risk of early death by 14 percent, with each extra 15 minutes reducing all-cause death rates by 4 percent.

　　另一項(xiàng)研究顯示，每天只需鍛煉15分鐘就可以延長(zhǎng)3年壽命，還會(huì)使過早死的機(jī)率降低14%。每多運(yùn)動(dòng)15分鐘就能使各種病因?qū)е碌乃劳雎氏陆?%。
